The office of the Independent Police Monitor said investigators in the shooting of an unarmed man in 2012 ignored or mischaracterized evidence to clear a former officer of any wrong doing.

The IPM released its final report Tuesday in the shooting death of Wendell Allen by Joshua Colclough. Allen was unarmed when Colclough shot and killed him during a drug raid at Allen's mother's house in Gentilly in 2012.

Colclough pleaded guilty to manslaughter in Allen's death. Colclough was sentenced to four years in prison as part of his plea deal. In 2013, the WDSU I-Team reported that at least part of the incident before the shooting was recorded by a small camera unit pinned to one of the other officers serving the warrant.

Colclough has been locked up for two years and is not eligible for parole for another year-and-a-half. On Monday, the I-Team reported he will return to court on Wednesday where he will ask a judge to reduce his sentence.

Tuesday's report by the IPM was the direct result of a long and in depth look into how the NOPD handled the case from start to finish.

"A lot of things were wrong with this investigation," said Susan Hutson with the IPM. " A lot."

Hutson called the raid was poorly planned and happened while there were six children at the home. The 34-page report also found the lead detective consistently misstated witness accounts and ignored crucial evidence.

An attorney for Allen's family said it was all part of a cover up. Allen's mother said she was disgusted when she learned of the IPM's report.

"Everything that I heard and should done about, it's wrong," Natasha Allen said. "How (do) I feel right now? My son would have still been alive if the police would have (done) their job correctly."

The NOPD issued a statement after the IPM released it's report:

"This incident was a tragic situation for the Allen family, the NOPD and the New Orleans community," NOPD Superintendent Michael Harrison said.

Harrison said some of the changes the NOPD has implemented since the Allen case have been improved training, supervision and resources for officers. That includes the implementation of cameras, which total 540 during the most recent count.

"Moving forward, I am committed to continuing to work with the (Department of Justice), federal Consent Decree Monitor and the Independent Police Monitor to ensure that we're doing everything we can to prevent these types of incidents from happening again," Harrison said.
